How to save processed data to text file using javascript?

Question

I'm using JavaScript for a project.

scan data from text file
process it
store back the processed data into text file

I have the data retrieval part working but I'm not able to store processed data through JavaScript.

I'm gathering the processed data into an array...

Is there any API available?

@Jordan Not necessarily. If he just has a string he wants to save that's fine... — Christian Stewart, Jun 30 '14 at 21:14
And if you are doing this in the browser, where do you want the text file to be? On the server? — Quentin, Jun 30 '14 at 21:15
@ChristianStewart If he had posted his code we wouldn't be waiting for him to update his question or post a reply before we can help him. :) — Jordan Running, Jun 30 '14 at 21:16
Its more of a export thing, like saving settings to local computer. — , Jun 30 '14 at 21:18
Yes, I m running this in my browser. The text file is stored on the server, output file gets downloaded. — , Jun 30 '14 at 21:19

You could use node.js.

I have a sample array as follows...

var cars = ["Saab", "Volvo", "BMW", "GMC", "Ford", "Honda"];

And I write to text file as such...

var fs = require('fs');
var file = fs.createWriteStream('cars.txt');
file.on('error', function(err) { /* error handling */ });
cars.forEach(function(v) { file.write(v.join(', ') + '\n'); });
file.end();
